Single Injection of Bupivacaine for Correction of Strabismus

Abstract To evaluate the effectiveness of a single injection of Bupivacaine (BPX) application for correction of eso/exodeviations this study has been performed. A retrospective review of ۳۰ patients with eso/exodeviations less than ۲۰ prism diopters (PD). Preoperative deviations were recorded in PD, using the alternate prism cover test. Postoperative angles at ۱ and ۳ months were measured in the same manner. The mean angle of deviation for near in all patients reduced significantly by ۳.۱ PD and ۲.۱ PD at ۱ and ۳ months. The mean angle of deviation for distance in all patients also decreased significantly by ۲.۳ PD and ۱.۹ PD at ۱ and ۳ months. As conclusions, single injection of BPX in a heterogeneous group of patients with horizontal strabismus caused a mild improvement in a qualitative success rate of ۳۷%.
